Abstract
A vehicle-to-vehicle (V2V) communication transponder for use in V2V communication, safety and anti-collision systems incorporating a location point store and a lane records store, wherein the lane records are constructed by the transponder from the point in the location point store, location points are received from other moving transponders, and lane records are shared between transponder response to a request. Separate source counts are kept for internally generated and shared lane records. Methods of sharing are described. Lane types are also derived from the location point store and other vehicle behavior. No central authority, road-side equipment, (RSU), or pre-determined lane maps are required. Embodiments include a hybrid protocol using both TDMA and CSMA. Some embodiments are free of MAC and IP addresses. Embodiments include equipped vehicles and V2V system using the transponder.
